DUMIING ATTACHMENT FOR VEHICLES.

Application filed July 25, 1921. Serial No. 487,455.

To all whom it may concern:

Be it known that I, ALLEN H. AsH, a citizen of the United States, residing at Lisbon, in the county of Grafton and State of New Hampshire, have invented certain new and useful Improvements in Dumping Attachments for Vehicles, of which the following is a specification.

This invention relates to a dumping attachment for wagons, and more particularly to such an attachment designed for ready application to a dump wagon or cart and for ready detachment. It has a particular application to vehicles used in road construction work, where a number of wagons, carts or trucks are employed in hauling road material, which must be spread in an even layer upon the roadway, and where by my invention a single attachment-is necessary to accommodate a number of such vehicles, the same being readily attached to each vehicle as it is ready for dumping. It will be understood that if the road material can be dumped in a regulated and even layer that the time and labor of hand spreading is saved and the expense of road construction greatly reduced.

The invention has for its object the provision of a dumping attachment for wagons and carts, which will permit of the use of a single attachment with a number of vehicles. A further object of the invention is the production in such a dumping attachment of means for regulating the amount of material to be dumped and the height of the dumped layer. A still further object of the invention is the improvement of the means for readily attaching and detaching such a dumping device to the vehicle.

Other objects and advantages of the invention will hereinafter appear in the following description and the novel features thereof will be particularly pointed out in the appended claims.

Like reference characters indicate like parts throughout the several figures of the drawings, in which I Figure 1 is a perspective of one form of my invention, the attachment in this case being shown upon the rear end of a wagon which employs a vertically sliding end gate;

Figure 2 is a longitudinal section of the rear end of such a wagon with my attach ment applied thereto;

Figure 4 1s a detail showing the pivoted lever controlling the locking rods for the adustable gate or gauge of the dump chute;

F1gure5 shows a modified form of vention, in which the dumping chute is applied to a wagon or truck provided with a pivoted end gate, provision being made in the form of the chute for the movement of sa d end gate, and the position of the parts being shown in dumping in dotted lines;

F lgure 6 is a chute removed from the wagon;

Flgure 7 is a detail showing parts of the guide and slidlng gate of the dumping chute of thls form of the invention, and

Flgure 8 is a view of the double hook detached.

The numeral 10 designates the body of a wagon, 11 the end standards, 12 the end cross beam, and 13 the brace between the standard and the cross beam. The numeral 14 designates as a whole the dumping chute, which in the form of Figure 1 is designed to fit snugly against the standards 11 and be held thereto by suitable means, compris ing in the present instance connections between the chute and the lower cross beam and between the chute and the end of the upper longitudinal frame members 15, 15.

The chute 1s made by uniting upper and lower substantially parallel boards 16 and 17 by side members 18 and 19, which are extended beyond the parallel boards 16 and 17 and have their lower portions cut away to provide road bearing surfaces when the material is being dumped, as shown clearly in Fi ure 2.

uitably securing the parallel boards 16 and 17 to the side members 18 and 19 are uprlghts 21, and suitably secured to the lower ends of these uprights and to the lower face of the board 17 is a cross bar 23, whose ends project beyond the side members and in proximity to the projecting ends of the cross beam 12 of the vehicle. The projecting ends of the cross bar and the cross beam are suit-ably connected together by means of easily removable double hooks 24:, which are of sufiiciently stout material to firmly hold the chuteat its lower portion to the inperspective of the dumping the cross beam 12; and as shown in Figure 8, this hook is formed with a nearly'complete loop 25 which encircles the ends of the cross bar 23. The body portion 26 of the hook bears upon the upper face of the cross beam and the hook end 27 takes over the cross beam 12 hearing against the lower face thereof.

Pivo-ted by suitable hinges 27, 27 to the board 16 is a gate or guage proper 28, swinging between the side members 18 and 19 and in its lowest position forming a closure for the chute. To the inner face of the side members 18 and 19 are attached suitably perforated arcuatestraps 29, which constitute with the rods 30, 30 and operating lever 31 the means for holdingthe gate or guage in its closed position or in any of the several open positions adjusted according to the thickness of material desired to be dumped upon the road. It Wlll be understood that the lever 31 is pivoted upon the upper face of the gate 28 and that the rods 30 are guided in their movement by loops 32 formed in the straps of the hinges 27 27. To the board 16 at either end thereof are secured the chains 33, 33, and the opposite ends of said chains are attached to the frame members 15, 15, and form suitable supporting means in addition to the hooks 24 for the chute.

It will be noted that the chute with its gate closed may constitute a tail gate for the wagon or the chute may be removed and the usual vertically sliding tail gate placed upon the wagon end to hold the material in place until the chute is applied at the point of dumping.

In the form of the invention shown in Figure 3, the bottom of the chute is constructed of a bottom board 34, and an inclined top board 35, the side members 36 being shaped to inclose the ends of these boards and having projecting runners 37, upon the inner faces of which are the arcuate locking plates 38. At the lower .end of the top board 35 the gate 39 is pivoted. This gate, like the one heretofore described, has the operating lever 31 and rods 33 constituting the means for regulating the depth of the layer of material being dumped.

Referring now to the form of the invention shown in Figures 5, 6 and 7, the chute is shown as applied to a dump truck having an upwardly swinging gate at its rear end, which gate is actuated upon the dumping of the vehicle in awell known manner. The chute of this form is not intended to be applied to the vehicle until there is need for dumping the load. It is adequately supported upon the end of the vehicle by means of the hooks 24, but it will be understood that additional supporting means may be provided if found desirable. The chute is composed of the substantially parallel upper and lower boards 40 and 41 and the side members 42 and 43, which are made relatively long in order that space ma be obtained between the wagon end HIM the board 40 for the easy movement of the pivoted tail gate 44 of the truck. To the side members 42 and 43 are attached the uprights 45 at a point corresponding with the rear edge of the board 40 and to these uprights is secured the vertical board 46, which cooperates with the pivoted gate of the vehicle to form the obstruction to the flow of material out of the body of the vehicle over the upper surface of the board 40.

The side members are extended to form inclined runners 47 and the upper edges of these extended portions are also inclined slightly and have attached thereto strap guides 48 for a sliding gate 49. It will be noted that this sliding gate is clamped by plates 50 passing through the guide straps and secured to the gate upon either side thereof. Any suitable means may be employed for holding the sliding gate in its adjusted position with relation to the guide straps and withrelation to the end of the chute. The clamping plates may be so tightly secured that the frictional engagement between the parts will besufficient for the purpose, but I have shown in addition the provision of apertures in the guide straps, into which apertures pinsmay be inserted at either side of the sliding gate.

As heretofore pointed out any of the forms of my invention may be attached to the vehicle at the time of dumping, and thereby saves the expenditure for a multiplicity of dumping chutes upon any one job of work. These chutes are easily applied to the usual forms of dumping vehicles.

In applying the chute to a vehicle the main means of support relied upon is the hook 24, which is so constructed with relation to the ends of the cross bar 23 and cross beam 12 that the end 23 may be released from its hook and the hook removed from the end of the cross beam 12, whereupon the other end of the chute can be obviously easily detached. In addition to this attachment of the chute to the vehicle, any suitable additional attachment can be provided, and as shown in Figure 1 the chains 33 are used to secure the upper portion of the chute to the upper portion of the vehicle end. This additional attachment may be found necessary where the chute is to remain upon the vehicle in its travel to and from the source of road material.

It will be noted that the end of the chute is madeto form runner sections as indicated by the numerals 20 in Figure 2, 47 in Figure 6. These runners not only take up the weight of the dumping material but provide with the movable gate a means for measuring or controlling the depth of dumped material. These runners are so formed that they will not track in the ruts formed by vehicles, and will insure that such ruts are-well filled in addition to an even layer of material spread.

The guage or gate is shown as pivoted in Figures 2 and 3 and as sliding in Figure 6, and constitutes the adjustable element of the chute whereby different depths of dumped material can be secured, as will be readily appreciated. The means for adjusting the ate with relation to the several associate parts have been described indetail and their operation will be clear from such description.

The form of chute of Figure 6 has no complete closure, that is, the gate in its movement does not completely close the mouth of the chute as in the other two forms. This is due to the fact that the form of Figure 6 is primarily used with a truck having an automatically opening tail gate and there is consequently no need of providing such a closure. However, the sliding gate in connection with its associated parts constitute an efiicient means for controlling the depth of dumped material, as will be clear from an inspection of the dotted line position of the truck body and chute in Fi re 5.

It will be understood that while I have described three forms of my invention they have been selected for the purposes of illustration only and that the invention may be embodied in sundry other forms and that changes may be made in the details of construction of these forms without departing from the spirit of the invention, as defined by the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is: I
